This detailed and weathered model of the Dai-X was created by CUG around 2006.
It is apparently around 30cm tall and uses parts from the MARK model kit as well as extra parts and decals for extra realism and detail.
Most images originally featured on timamini.com

I managed to 'convince' the tinamini image processor to let me have slightly better quality versions of the images than those on their own site.
